The mineral resource estimate has been calculated using the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definitions Standards for mineral resources in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects.
Mineral resources which are not mineral reserves do not have demonstrated economic viability.
Mineral resources update for Marban gold deposit is effective date: November 16, 2011.
Mineral resources update for Norlartic and Kierens deposit is effective date: December 1, 2009.
1: Rounded to nearest 10 thousand.
2: Rounded to nearest 1 thousand.
3: 0.5 g/t Au cut-off on resources from surface to 200 metres vertically and 2.5 g/t Au cut-off below 200 metres.
4: Mineral resource estimate reported by MDA Dec 1, 2009.
Outlook from Phase 2 drilling program
The results of 90 holes and 9 extensions of previous holes of the Phase 2 of the drilling program have successfully confirmed the extension of the different zones of the Marban mineralized system (see the news releases dated March 1, April 26, June 12, and August 15, 2012). The objectives of this program on the Marban deposit were to improve the quality of the near surface resources, developing a mineral inventory below a depth of 250 vertical metres and outside the known lateral extension.
An updated mineral resource will be produced in order to integrate the results of the Phase 2 drilling program in the resource estimate.
The preliminary metallurgical testwork at Marban indicates a favourable recovery between 95.4% and 97.6% for the ore cyanidation test (see news release dated April 24, 2012). The Bond ball mill testing indicated the ore fell in the medium soft to medium range of hardness compared to the SGS database (10.1-10.9 kWh/t).
A baseline environmental study has been initiated and being prepared by Golder Associates and should be completed by the end of the year.
A third phase of drilling will be initiated later this month. There is still $9M to be spent in the earn-in option with Aurizon.
Aurizon can earn up to a 65% interest the Marban Block property under the terms of an option and joint venture agreement dated July 5, 2010, between NioGold and Aurizon. The initial 50% interest can be earned by incurring expenditures of $20 million over three years, completing an updated NI 43-101 compliant mineral resource estimate, and by making a resource payment for 50% of the total gold ounces defined by the mineral resource estimate. NioGold remains the project operator during the initial earn-in period (see news release dated July 6, 2010).
Scientific/Technical Info, Qualified Persons and QA/QC
Information of a scientific or technical nature in this news release has been reproduced from Aurizon's news release, which information was prepared by or under the supervision of Ghislain Fournier P.Eng., Technical Services General Manager of Aurizon and Martin Demers P.Geo, Exploration Manager of Aurizon. The current mineral resource estimate on the Marban deposit was completed by Yann Camus Eng., of SGS Canada Inc. - Geostat, an independent Qualified Person under NI 43-101 guidelines, using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council on December 11, 2005. The effective date of the estimate is November 16, 2011. NioGold does not, at present, know if, how and to what extent any qualified persons at Aurizon have verified the data underlying the scientific and technical information disclosed in Aurizon's news release and reproduced in this news release. NioGold will attempt to verify the data once Aurizon files its technical report in support of its news release.
